Re: Allergic reaction to... Snow?
I would give her a bath paying special attention to the head, neck, sides, and feet. Not a down to the skin bath but one that cleans the top layer of hair. I'm thinking she rubbed - messed with - or otherwise got into something she wasn't suppose to have. If so, then with the irritation on her face and such, it keeps bothering her and keeps reoccurring.
